My invention relates to a radial bearing and has for its principal'object to afford a 5 port a spindle, receiving radial thrust therefrom, and also permit endwise movement of the spindle.

In mother aspect, the invention has for its PUEYOSB to provide a hall bearin for m a spin e or similar unit, such that the ails can move in two directions at right angles to each other, as for instance, around the peri hery of the spindle and also endwise of espmdle.

More particularly, the invention is intended to afiord an efiicient and practicable radial ballbearing for a spindle, having a slight reciprocating motion as in sand-papermachinerg. e

e inven on also has for an object to provide a construction involving inner and outer ball engaging members forming a radial bearing and arrangedso that one of the said members, together with the balls can move 7 toward and from the sides oi the other member.

- With these and other ends in view, the in vention comprises the construction and combination of parts that will appear clearly so from the following description, when read in conjunction with the accompanying drawings, the novel features being pointed out in the claims following the description.

F igure 9 is an enlarged'sectwnal view of a rtion of Figure 7, and

rgure '10 is a detail perspective view, partially broken away and with the balls omitted, of the bearing illustrated in Figure 7 to 9 inclusive.

It has heretofore been impracticable to emgoy auradial ball bearing in connection w: a reciprocating spindle, and one of the ch1 e accomplishments of my invention is in gaining the advantages of a ball bearing in con unction with a reciprocatory spindle, as wel as the fact that I obtain a bearing in which the balls are Eermitted movement in two dlrections at rig t angles to each other, since this characteristic has possible points of advantage independently of the necessity of accommodating the bearin to a reciproeating unit. The specific disc osures herein set forth are intended only as illustrative examples of man possible applications of the invention, an it is further to be understood that while I have shown and described the hearing as including balls this term is intended to include any anti-friction members such as-rollers, where they may be substituted for the balls of the present embodimen Figures 1 to 6 illustrate a form of bearing embodying my invention in which the balls I and ball retainer are movable in a direction at ri ht angles to the radial thrust, or towar and from the sides of one of the ball engaging members, such an arrangement being advanta ous when applied to a recipro eating spin e structure, such as shown in Figure 1. This view illustrates a portion of a sand-papering machine, including a sandpapering roll 1 mounted on a reciprocating spindle 2 that is operated from a rock arm 3 ivoted upon the bracket 4, the rock arm 3 ein actuated by link 5 and eccentric 6. In mac ines of this articular character, ball mo bearing mountings or the spindle have not been used owin to the reciprocating motion of the spindle, ut withthe present arrangepossible for the spindle to have longitudinal motion r and eifective relation with ment, is is the necessary maintain pro the balls of e bearing. p The. bearings are mounted in a box 10 and comprise the stationary outer ball ens s s members and still 11 and inner ball engagno o L l ,1 v gotha r with the inner members movement Qoinrd md'hom of a rolli motion troupe! lihzjn flq ll l5 11 mi usual in 'alboll hearings:
